Application filed January 2, 1914. Serial No. 810,094.

, To all whom it may concern Be it known that I, ROBERT I. MoKrssaon,

a citizen of the United States, and a resident and Improved Liquid-Fuel-Gas Generator, of which the following is a full, clear, and exact description. v I My invention relates to a generator for the production of heat for domestic and general. use.

Gne of the principal objects of this invention is to provide a reliable, economicaland efficient means for converting liquid fuel into gas combined with adjustable means for mixing the right amount of air with the gas to insure perfect combustion.

A further object of the invention is to provide in the construction and arrangement of'the mechanical parts a trough system of cruciform structure for distributing the liquid fuel under the different parts of the generator whereby a more satisfactory initial priming or heating of the generating pipes is obtained for the purpose of starting tillilelprocess of generating gas from the liquid Another important object is to provide an auxiliary burner so disposed and associated with the generator, that the gas from said generator, when in operation, may be turned on through a specially arranged controlling valve and conveyed through a connecting pipe to the auxiliary burner by which it is re-superheated just before it is delivered from the jet port, thus assuring a thorough generation and a clean flame at the immediate point of applied heat and effectually avoiding the possible use of gas that may have partially re-condensed while passing through the connecting pipe between the generator and the auxiliary burner.

With the foregoing and other objects in view the invention consists of the construction, mechanism and novel combination of parts hereinafter more. fully described, illus trated in the accompanying drawings, and pointed out in the claims hereto appended, it being understood that various changes in form, structure, proportion, size and mmo-r details, within the scope oflmy claims, may be-resorted tov without departing fromthe spirit of or sacrificing any of the advantages of the invention.

' Figure 1 is aside elevation of the prmcipal p'arts of my invention, the base pan beof New Orleans, in the parish of Orleans. I and State of Louisiana, have invented a new ing in longitudinal section; Fig. 2 is a plan view of the same; 'Fig. 3 is a perspective viewof one of the air shafts and pipe supports; Fig. 4 is a detail perspective view of a portion of thepan showing the adjustable air openings; and Fig. 5 is a perspectivev view of a slight modification of the same invention.

In carrying out the objects of my invention a fuel supply pipe is provided connectmg the generator with any suitable source of liquid fuel supply (not shown), and the flow of fuel is controlled with any suitable valve. The fuel tank may be of any suitable size :or shape and placed in any convenient location, either near to or some distanceaway from the generator and operated either by gravity fiow or air pressure.

Liquid fuel of any suitable as kerosene, distillate, etc., is conveyed to ch aracter, such the burner through a'pipe 10 and thence past a control valve 11 intoand through a horizontal pipe 12 which may lie comparatively close to and under the base pan 13. From the pipe 12 the fuel is carried upwardly by means of a pipe 14 and thence through a horizontal elevated vaporizer pipe 15 from the end of which it passes through a short inclined pipe 16 and thence through a series of superheating or retort pipes 17, 18 and 19 constituting the three sides of a rectangle. Thence. the fuel passes downwardly through a short pipe,20 into the nozzle pipe 21 which lies in a horizontal position and substantially central with respect to the retort pipes above described. The nozzle pipe 21 lies in or is supported by a vertical casing or air-shaft 22, shown in Figs. 1, 2 and 3 as rectangular in outline and having an open bottom communlcatin with a rectangular air opening 23 formed 1n or through the base pan 13. Said vertical air-shaft structure 22 said arms 24 support the nozzle pipe 21 and the other two 24, preferably at right angles to the first, are open at their tops and ends. The nozzle upwardly cm the axis of the air-shaft and is adapted to deliver the liquid so that it will .spread over the nozzle pipe 21 when cold I and be conveyed along all four of the arms of the distribute'r24u Said fuel, therefore, will fill the arms of said distributer, and will plpe 21 is provided preferably with a single jet hole 21 which is directed also flow from the ends thereof and saturate I would have it understood also, in this connection, that while I describe the retort or superheatmg system as being rectangular, being made up largely of the pipes 17, 18

and 19, any other form that is found suit .able may be used, without departing from the real invention covered by the claims. It will be observed that all or" the vaporizmg, generating and superheating pipe ele- -ments leading beyond the valve 11 lie above the base pan and hence are subjected to the heat derived from the burning fuel delivered originally into the ing troughs.

At 25 I show a deflector, preferably concaved, secured centrally of the system of pan from the distributpipes to the pipe 15.

To start generating, the fuel is turned on and a small amountis permitted to escape through the ct hole 21- to be distributed by the system of cruciform troughs all around under the pipes in the base pan, then ignited .and all of the pipes of the generator are thus heated initially. Then 'the fuel is turned on again and the flow is regulated. The fuel in passing through the top pipe 15 is vaporized,,the vapor in "passing around through the superheating retort pipes l7,

l8 and His reduced to a clean gas which escapes through the jet hole in the capped nozzle pipe under the pressure caused by the expansion of the heated fuel, and shoots up with "some force against the adjustable 0011- caved flame spreader and deflector. 25 sus pended from the overlying vaporizing pipe. The vaporizing pipe is thus kept hot and the heat is deflected back against the surrounding superheating pipes, thus making the -gas generating continuous until the valve controlling the admission of fuel is shut off.

The base pan is provided with adjustable air supply controlling devices and the entire construction is so combined and arranged that the mixture of air with the gas can. be regulated so as to insure a perfect combustion. V 0

Under each generator and supporting the same is an air shaft either round or square provided with notches in which are mounted quadrangular troughs with open ends for distributing the igniting fuel in the base pan and around under the vaporizing pipes and superheating retorts.

Each spreader or deflector 25 is attached to the vaporizing pipe 1 5;by means of a clamp 25 whereby the deflector may be by means of a plurality of wings 23 which, i

being constructed preferably of sheet metal, are adapted to be bent toward or from the center of the passage according to the requirements of any particular user or according to the variable conditions to be met in general use, having reference to the varying drafts of different stoves, furnaces, fines, etc. The air-shaft may be secured in place. by means of lips or lugs 22 adapted to pass through and clench beyond corresponding holes 22- 'in the base pan. I also provide any desired number of small openings 26 along the sides of the base pan, the size of which is adjustable also as by means of adjustable flanges 26*. These openings 26 may be used in connection with those indi cated leading directly through the center of the air-shaft.

Figs. 1 and 2 show a plurality, of generators leading from tliesame supply pipe 10, each of said generators being controlled by its own independent val e' 11. The descrip-. tion of one generator cor'i'struction given above is applicable to any number of such generators. In Fig. 5 I show a slngle generator arrangement, the fuel to which is delivered by means of a pipe 10'. The a rshaft 22, as above stated, is circular or cylindrical, and the distributing troughs 24 are curved in cross section. The adjustable members 23 for controlling theamount pf air admitted upwardly through the airsliaft may in this form he" segmental and of. any suitable number. I i" As shown in Fig. 5, an extension 27 may be formed leading from the nozzle'pipe 21 and connecting with an upwardly extending p pe which is further extended into a peculiar loop construction forming an auxiliary burner 28 through which the gas is forced from said pipe 27 and re-superheated before it is delivered from the jet port 27. 'The elevated hori'zhntal section of this auxiliary burner 28 supports a deflector 25 against which the flame from said jet port 27 1mpinges. The nozzle pipe of the auxiliary burner may be further extended to provide additional auxiliary burners if desired, and the gas may'be cut off itrom the /auxiliary burners means of any suitable type .of valve 29 having a stem 30 Many required length. When used, for instance, in a cooking stove, with the base pan 13 lying in or near the bottom of the fire box of such stove, the generator, as above described, may constitute the burner for the front holes of the stove, and the extension 27 may lead back over-the top of the oven and provide a suitable auxiliary burner for the rear holes at 29"1 show a small pipe or hollow wire tapping the nozzle pipe 21 and leading downwardly through the bottom of the base pan and thence in any direction whereby a portion of the generated gas may be utilized for use asa light or for other purposes.
